> During longevity testing of the encryption-at-rest version of Accumulo, we
> would occasionally see IOExceptions that took the form of Zlib throwing an
> "incorrect header check" exception. These exceptions occurred only after a
> few hours of testing, during minor and major compaction of various RFiles.
> Downloading and examining the RFiles in question showed no obvious
> deformities within the RFile structure.
> Some careful debugging later, the crux of the problem turned out to be some
> calls to read() when readFully() should have been used.
> Patch coming forthwith. Also included in this patch is another secret key
> handling strategy that caches the secret key from HDFS when first read.
